6.7.2 Behavior in the event of an error (with standard setting)
The behavior of the servo amplifier always depends on the current setting of a number of different
parameters (e.g., ACTFAULT, VBUSMIN, VELO, STOPMODE, etc.; see online help). The diagram
shows the startup procedure and the procedure that the internal control system follows in the event
of one or more electrical supply phases failing, assuming that the standard parameter settings
apply.
(F16/F19 = error messages Mains BTB /input phase, F05 = error message Undervoltage)
Even if there is no intervention from an external control system (in the example, the ENABLE signal
remains active), the motor is immediately braked using the emergency stop ramp if an input phase
error is detected and assuming that no changes have been made to the factory setting
(ACTFAULT=1).
